Long ago, humans were considered to be the first to start injecting carbon dioxide (CO2) into the environment. They used to burn fossil fuels such as gas, oil, and coal. The atmospheric CO2 level was significantly increased when the Earth came out of its final ice age. A number of scientists were previously supposing that the supply of this carbon was coming from the sea.
However, researchers were not able to verify how the carbon made it out of the ocean and into the atmosphere. This was said to be one of the most significant science mysteries.
The latest study, published earlier in the journal Nature Geoscience, offers few of the most convincing indications about how it happened—a “flushing” of the deep Pacific Ocean triggered by the speeding up of water motion patterns that begin around Antarctica. Researchers concerned that this phenomenon might repeat itself again, probably increasing as well as hastening human-caused climate change.
On a similar note, the ocean is considered to be an incomprehensibly huge and very wild place. It is supposed that the sea offers ample room to accept the human influence. The latest study published in the journal Current Biology highlights that only 13% of the oceans are still considered as wild places, with a slight indication of human influence or interference or typically free of human disturbance.
Essentially, the study reveals that about 87% of the planet’s oceans are not functioning as they should. This is owing to the impact of human activities such as shipping, overfishing, seafloor mining, fertilizer getting into the seas, and so on. This indicates the poor functioning of oceanic ecosystems.
According to researchers, the human interference might probably lead to devastating consequences for marine life. This includes the fish that feeds billions of individuals, and reef development that not only supplies surf but also protects coastlines.
